Abstract: A system and method is provided for discovering capabilities of a first device communicating with a second device using a telecommunications network. The first and second devices are registered at a service platform. The first and second devices access the service platform through first and second core networks. At the first core network, a request is received from the second device for discovering capabilities of the first device. The first core network determines a first status indicator of the first device. The request is routed from the second device to an application server. The first status indicator of the first device is identified by the application server and a second status indicator of the first device is determined. A response is sent from the application server to the second device, the response containing feature tags describing a set of services supported by the first device.

Abstract: According the present invention there may be provided a method of determining which user device (UD) of a plurality of user devices should receive a Session Initiation Protocol, SIP, request (RQ) for a communication service on a telecommunications system, the system comprising: a plurality of user devices (UD) adapted to run a communication service; an application server (AS) in communication with the plurality of user devices on which there is comprised a registry of the plurality of user devices (UD), the registry comprising associations between user devices and SIP instances, each user device being associated with a respective user identity; and, a telecommunication network in communication with the plurality of user devices (UD) and with the application server (AS), wherein the method comprises, at the application server (AS): receiving a SIP request (RQ) for establishing a communication service, the SIP request intended for a user identity from the telecommunication network; and, dynamically determining

Abstract: Management of a call between a calling party that is a mobile terminal in a first cellular network and a called party that is a mobile terminal in a second cellular network is provided by: receiving at an Application Server, AS, of the first cellular network a request to establish a call with the called party from the calling party, the called party being identified in the indication by a circuit-switched identifier; identifying a registration for the called party in the first cellular network using the circuit-switched identifier for the called party, the registration providing a packet-switched identifier for the called party; and setting up a call between the calling party and the called party of the first cellular network by initiating a packet-switched connection from the AS in the first cellular network to the called party in the second cellular network using the packet-switched identifier for the called party.

Abstract: A machine (1) in the TCP/IP network (2) performs a request regarding a consultation or modification of at least one mobile telephone network subscriber parameter; it is characterized in that it comprises means (5) for receiving the request made and means (5) for extracting the parameters included in said request and which are necessary for being able to attend to it. It comprises storage means (7) of at least one parameter pertaining to the different mobile telephone network subscribers (3) and means for sending the response to the request made in order to obtain and send the obtained information in the case that the request made is a consultation regarding the stored parameter. It comprises means (6, 8, 9 and 10) for obtaining the necessary mobile telephone network parameters so that the request is attended to by said mobile telephone network (3) in order to make the request to the network (3) when the request made is not contained in the means (7).

Abstract: A system which allows the Internet address assigned to a destination equipment to be obtained, starting from its identification name, such as is carried out conventionally with the DNS protocol, and which also allows different information to be obtained on the destination equipment starting from its identification name, as for example can be information contained in databases of mobile telephony networks or in a database belonging to a data network. The system comprises a request administration means which is connected to a means of analysis of at least one parameter of the DNS protocol and at least one database message composition/reception module that is connected to at least one external database and also including means of analysis of the answer of the at least one external database and of an internal database to deliver the information requested by using the DNS protocol.
